Messier 61 (also known as M61 or NGC 4303) is an intermediate barred spiral galaxy in the Virgo Cluster of galaxies. It was first discovered by Barnaba Oriani on May 5, 1779, six days before Charles Messier discovered the same galaxy. Messier had observed it on the same night as Oriani but had mistaken it for a comet. [5] Its distance has been estimated to be 45.61 million light years from the Milky Way Galaxy. It is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. [6]

Properties

M61 is one of the largest members of Virgo Cluster, and belongs to a smaller subgroup known as the S Cloud. [7] [8] The morphological classification of SAB(rs)bc [3] indicates a weakly-barred spiral (SAB) with the suggestion of a ring structure (rs) and moderate to loosely wound spiral arms. [9] It has an active galactic nucleus [10] and is classified as a starburst galaxy containing a massive nuclear star cluster with an estimated mass of 105 solar masses and an age of 4 million years, [11] as well as a central candidate supermassive black hole weighing around 5×106 M solar masses. [12] It cohabits with an older massive star cluster as well as a likely older starburst. [11] Evidence of significant star formation and active bright nebulae appears across M61's disk. [13] Unlike most late-type spiral galaxies within the Virgo Cluster, M61 shows an unusual abundance of neutral hydrogen (H I). [14]

Extragalactic supernovae

Eight extragalactic supernovae have so far been observed in M61, making it one of the most prodigious galaxies for such cataclysmic events. [15] [16] [5] These include: SN 1926A (type II-K, mag. 14), [16] SN 1961I (Type II, mag. 13), [16] SN 1964F (Type II, mag. 14), [17] SN 1999gn (Type II, mag. 16), [18] SN 2006ov (Type II, mag. 14.9), [19] SN 2008in (Type II, mag. 14.9), [20] SN 2014dt (type Ia-pec, mag. 13.6), [21] and SN 2020jfo (Type II, mag. 16).

Messier 100 is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years, and being about 60% as large. It was discovered by Pierre Méchain in 1781 and 29 days later seen again and entered by Charles Messier in his catalogue "of nebulae and star clusters". It was one of the first spiral galaxies to be discovered, and was listed as one of fourteen spiral nebulae by Lord William Parsons of Rosse in 1850. NGC 4323 and NGC 4328 are satellite galaxies of M100; the former is connected with it by a bridge of luminous matter.
